Abstract
A novel experimental installation is described in which the traditiona l method of detecting extensive air showers with scintillation counter s is significantly extended by the addition of limited streamer tube h odoscopes (LST) and layers of resistive plate counters (RPC). Runs wit h the scintillator array, GREX, at Haverah Park have demonstrated the power of the LST hodoscopes to determine the direction of arrival of m uons, electrons and photons in air showers while the RPC system permit s the relative arrival time of individual particles and the temporal t hickness and structure of the shower disc to be obtained. The potentia l of these technical advances for studying the longitudinal profile of air showers produced by primaries of about 1000 TeV is briefly discus sed. First measurements of thickness and time profile of EAS front are also reported.
